Dear Mr. Hahn!

I am a publisher of a magazine "Československá vlaková pošta" (Czechoslovakian Train Post) and a co-founder of the currently created The Museum of Train Post Offices. I have a request for you. Could I use this photo in my journal? Please email me at vlakovaposta@email.cz.
Thank you very much.

Yours sincerely,

Petr Študent - chief editor, curator
